Thanks for the grat plugin!
Just one suggestion to improve it a little bit. When you build excerps you cut strings exactly at 252-nd char. This results in showing "black-diamond-question-mark" sometimes when cutting cyrillic strings. In order to work this out, you can cut string at a nearest space.
So, this is your original string (CatList.php):
$lcp_excerpt = substr($lcp_excerpt, 0, 252) . '...';
And my suggestion is to replace it with this one:
$lcp_excerpt = substr( $lcp_excerpt, 0, strrpos( substr( $lcp_excerpt, 0, 252 ), ' ' ) ) . '...';
So, it just cuts excerpt at the nearest space before 252nd char.
